Rotary power overhead transmission line deicing device

Abstract

The invention discloses a rotary power overhead transmission line deicing device comprising a back box and a deicing rod. An induced draft fan is installed on the center of the right end inside the back box. The lower end of the back box is connected with a hot air pipe. A lead screw is installed in the deicing rod. A driven wheel is installed on the center of the lower end of the lead screw. A driving wheel is engaged with the right end of the driven wheel. A lifting block is installed on the center of the upper end of lead screw. Lifting rods are installed on the left and right ends of the lifting block. A first connecting rod is hinged to the tail end of the lifting rod. A second connecting rod is hinged to the upper end of the first connecting rod. A deicing ring is connected to the upper end of the second connecting rod. A clamping ring is arranged on the inner side of the deicing ring. Deicing teeth are uniformly arranged on the inner side of the clamping ring. Hot air holes areuniformly disposed on the center of the clamping ring. Fixing plates are installed at both ends of the middle of the deicing rod. Fixing rods are mounted on the upper ends of the fixing plates. The rotary power overhead transmission line deicing device clamps a transmission line by the deicing ring, and doubly deices an ice layer on the transmission line, improves a deicing effect, is easy to operate, meets the need for deicing the transmission line, and is practical.

Description

technical field [0001] The invention relates to the technical field of electric power auxiliary equipment, in particular to a rotating deicing device for overhead power transmission cables. Background technique [0002] With the rapid development of my country's economy, there are more and more ultra-high-voltage large-capacity transmission lines. In winter, due to the icing problem of the transmission line caused by the climate, the load bearing of the transmission line increases. If the weight of the transmission line covered with ice exceeds the load-bearing range of the transmission line or the tower, it will cause accidents such as disconnection and tower collapse, which will damage the power transmission system and cause great losses to the national economy. Transmission line accidents seriously threaten the reliability of power transmission and communication networks. In order to solve the above problems, it was proposed to input a larger current to the power grid t...

In winter, due to the icing problem of the transmission line caused by the climate, the load bearing of the transmission line increases

If the weight of the transmission line covered with ice exceeds the load-bearing range of the transmission line or the tower, it will cause accidents such as disconnection and tower collapse, which will damage the power transmission system and cause great losses to the national economy. Transmission line accidents seriously threaten the reliability of power transmission and communication networks

In order to solve the above problems, some people propose to input a large current to the power grid to increase the temperature of the wires to prevent icing. However, due to the low temperature, it will consume a lot of electric energy to prevent icing, and there are still technical obstacles.

[0003] In the current mechanical deicing machine, the method of cutting with a knife or scraping a pulley is mainly used for deicing. This method is easy to cause great damage to the cable, and the operation of these devices is relatively complicated. The technical requirements for electric maintenance personnel Too high, and for the power transmission cables erected on uneven ground, these devices cannot reach at all
